Featuring 200k\u03a9 resistance with \u00b11% tolerance, 0.1W power rating at 70\u00b0C, and \u00b1100ppm\/\u00b0C temperature coefficient, it offers high stability and reliability for automotive and industrial precision applications. The RK73H series provides tighter tolerance and lower TCR than the general-purpose RK73B series, making it suitable for feedback networks, gain setting, and voltage divider reference circuits where ratio accuracy is critical.","working_principle":"The RK73H1JTTD2003F operates as a precision fixed thick film resistor using metal glaze thick film deposited on an alumina ceramic substrate. The resistive element is a ruthenium-oxide-based metal glaze layer that provides excellent long-term stability and low TCR of \u00b1100ppm\/\u00b0C. Laser trimming adjusts the resistance to the precise 200k\u03a9 value within \u00b11% tolerance. The \u00b1100ppm\/\u00b0C TCR means the resistance changes by no more than 0.01% per degree Celsius, or \u00b11% over the full -55\u00b0C to +155\u00b0C range\u2014half the drift of the standard RK73B series (\u00b1200ppm\/\u00b0C). The blue protective coating with 4-digit marking (2003 = 200k\u03a9) distinguishes the precision series from the general-purpose black-body RK73B. The RK73H achieves \u00b11% tolerance through tighter process control and screening during manufacturing.","pin_description":"
